NAME

ecm.eclass - Support eclass for packages that use KDE Frameworks with ECM.

DESCRIPTION

This eclass is intended to streamline the creation of ebuilds for packages that use cmake and KDE Frameworks' extra-cmake-modules, thereby following some of their packaging conventions. It is primarily intended for the three upstream release groups (Frameworks, Plasma, Gear) but also for any other package that follows similar conventions.

This eclass unconditionally inherits cmake.eclass and all its public variables and helper functions (not phase functions) may be considered as part of this eclass's API.

This eclass's phase functions are not intended to be mixed and matched, so if any phase functions are overridden the version here should also be called.

SUPPORTED EAPIS

TRANSITIVELY PROVIDED ECLASSES

cmake virtualx

FUNCTIONS

ecm_punt_kf_module <modulename>: Removes a Frameworks (KF - matching any single-digit version) module from a find_package call with multiple components.
ecm_punt_qt_module <modulename>: Removes a Qt (matching any single-digit version) module from a find_package call with multiple components.
ecm_punt_bogus_dep <dependency> or <prefix> <dependency>: Removes a specified dependency from a find_package call, optionally supports prefix for find_package with multiple components.
ecm_pkg_pretend: Checks if the active compiler meets the minimum version requirements. phase function is only exported if KDE_GCC_MINIMAL is defined.
ecm_pkg_setup: Checks if the active compiler meets the minimum version requirements.
ecm_src_prepare: Wrapper for cmake_src_prepare with lots of extra logic for magic handling of linguas, tests, handbook etc.
ecm_src_configure: Wrapper for cmake_src_configure with extra logic for magic handling of handbook, tests etc.
ecm_src_compile: Wrapper for cmake_src_compile. Currently doesn't do anything extra, but is included as part of the API just in case it's needed in the future.
ecm_src_test: Wrapper for cmake_src_test with extra logic for magic handling of dbus and virtualx.
ecm_src_install: Wrapper for cmake_src_install. Drops executable bit from .desktop files installed inside /usr/share/applications. This is set by cmake when install() is called in PROGRAM form, as seen in many kde.org projects.
ecm_pkg_preinst: Sets up environment variables required in ecm_pkg_postinst.
ecm_pkg_postinst: Updates the various XDG caches (icon, desktop, mime) if necessary.
ecm_pkg_postrm: Updates the various XDG caches (icon, desktop, mime) if necessary.

ECLASS VARIABLES

VIRTUALX_REQUIRED ?= manual: For proper description see virtualx.eclass manpage. Here we redefine default value to be manual, if your package needs virtualx for tests you should proceed with setting VIRTUALX_REQUIRED=test.
ECM_NONGUI: By default, for all CATEGORIES except kde-frameworks, assume we are building a GUI application. Add dependency on kde-frameworks/breeze-icons or kde-frameworks/oxygen-icons and run the xdg.eclass routines for pkg_preinst, pkg_postinst and pkg_postrm. If set to "true", do nothing.
ECM_KDEINSTALLDIRS ?= true: Assume the package is using KDEInstallDirs macro and switch KDE_INSTALL_USE_QT_SYS_PATHS to ON. If set to "false", do nothing.
ECM_DEBUG ?= true: Add "debug" to IUSE. If !debug, add -DQT_NO_DEBUG to CPPFLAGS. If set to "false", do nothing.
ECM_DESIGNERPLUGIN ?= false: If set to "true", add "designer" to IUSE to toggle build of designer plugins and add the necessary BDEPEND. If set to "false", do nothing.
ECM_EXAMPLES ?= false: By default unconditionally ignore a top-level examples subdirectory. If set to "true", add "examples" to IUSE to toggle adding that subdirectory.
ECM_HANDBOOK ?= false: Will accept "true", "false", "optional", "forceoptional". If set to "false", do nothing. Otherwise, add "+handbook" to IUSE, add the appropriate dependency, and let KF${_KFSLOT}DocTools generate and install the handbook from docbook file(s) found in ECM_HANDBOOK_DIR. However if !handbook, disable build of ECM_HANDBOOK_DIR in CMakeLists.txt. If set to "optional", build with -DCMAKE_DISABLE_FIND_PACKAGE_KF${_KFSLOT}DocTools=ON when !handbook. In case package requires KF5KDELibs4Support, see next: If set to "forceoptional", remove a KF${_KFSLOT}DocTools dependency from the root CMakeLists.txt in addition to the above.
ECM_HANDBOOK_DIR ?= doc: Specifies the directory containing the docbook file(s) relative to ${S} to be processed by KF${_KFSLOT}DocTools (kdoctools_install).
ECM_PO_DIRS ?= "po poqm": Specifies directories of l10n files relative to ${S} to be processed by KF${_KFSLOT}I18n (ki18n_install). If IUSE nls exists and is disabled then disable build of these directories in CMakeLists.txt.
ECM_QTHELP: Default value for all CATEGORIES except kde-frameworks is "false". If set to "true", add "doc" to IUSE, add the appropriate dependency, let -DBUILD_QCH=ON generate and install Qt compressed help files when USE=doc. If set to "false", do nothing.
ECM_TEST: Will accept "true", "false", "optional", "forceoptional", "forceoptional-recursive". Default value is "false", except for CATEGORY=kde-frameworks where it is set to "true". If set to "false", do nothing. For any other value, add "test" to IUSE (and for KF5 DEPEND on dev-qt/qttest:5). If set to "optional", build with -DCMAKE_DISABLE_FIND_PACKAGE_Qt${_KFSLOT}Test=ON when USE=!test. If set to "forceoptional", punt Qt${_KFSLOT}Test dependency and ignore "autotests", "test", "tests" subdirs from top-level CMakeLists.txt when USE=!test. If set to "forceoptional-recursive", punt Qt${_KFSLOT}Test dependencies and make autotest(s), unittest(s) and test(s) subdirs from *any* CMakeLists.txt in ${S} and below conditional on BUILD_TESTING when USE=!test. This is always meant as a short-term fix and creates ${T}/${P}-tests-optional.patch to refine and submit upstream.
KFMIN: Minimum version of Frameworks to require. Default value for kde-frameworks is ${PV} and 5.106.0 baseline for everything else. If set to >=5.240, KF6/Qt6 is assumed thus SLOT=6 dependencies added and -DQT_MAJOR_VERSION=6 added to cmake args.
KDE_GCC_MINIMAL: Minimum version of active GCC to require. This is checked in ecm_pkg_pretend and ecm_pkg_setup.
